The Rock Krawler RRD Shocks fluted aluminum body gives the advantage of weight reduction without sacrificing strength. Which not only make this shock the lightest remote reservoir shock in its class, it also provides a surface area greater than most 3 inch bodied shocks. The fluting provides the structure required to ensure the aluminum cylinders are as strong, if not stronger than their steel counterparts. The shock bodies are also treated with a military grade hard anodized coating so you never have to worry about corrosion. A high quality DU bearing provides the bearing surface for the massive Nitrotec Steel shaft. And unlike chrome plated shafts these Nitrotec steel shafts are bare so you never have to worry about pitting or flaking potentially destroying the seals. While a billet aluminum valve circuit with digressive valving controls the dampening, redundant sealing technology keeps the shock oil where is belongs. The shock oil is formulated for fade-free dampening and smooth rebounds. Its high viscosity index and shear stability controls shock fade.
